    Cons

    • Since they do not have an occupancy component to them you are expected to rely on scheduling, however you cannot schedule by day, only preset buckets of time that go across every day.GTIceman

      Bought two of these, one for my office, one for my younger child's bedroom. My plan? Simple - schedule the one in my office as the primary sensor while the kids are in school (work from home), and schedule the one in my daughter's bedroom to be the primary during the night (keep her comfortable), and then for pre/post school and on the weekends when they're awake, use the downstairs main thermostat as the primary. Here's what actually happened. Bought two of these sensors unpacked, scanned the QR code (note: if you buy more than one and take the tabs out and get confused as to which QR code goes to which sensor, take a coin and unscrew the back, there is a QR code on the inside as well. Had to apply more strength/pressure on unscrewing the back ring than I had anticipated...), added the new sensor to my Nest account/system. Tried to connect to the thermostat downstairs, kept saying it couldn't establish a connection, move the sensor closer. Kept moving it closer and closer until I literally rested the sensor on top of the actual thermostat and it still said it couldn't make a connection. That's when I unscrewed the back of the sensor trying to make sure the battery was seated properly, etc. It was. Tried again, failed. Removed the sensor from the nest account, tried to re-add and re-sync, no luck. Then I realized that (for the first time in probably ever...) the main thermostat was not connected to my WIFI network, and hadn't been for about 2 hours. Seems like something the setup of this remote sensor should check for... like maybe a "hey, seems like your thermostat has lost its connection to your home network, and that's required for setup of this newly added device". I rebooted the main thermostat and the connections worked flawlessly, even through a few walls. If you have the nest cameras (I have one in each kid's room), and you use the default labels "office, den, kids room, bedroom, whatever" and the labels match, it will show you the temperature in the room where the camera is, which is kind of a cool feature. Anyway, then when it came time to schedule the priority of all the sensors I was a little disappointed with how "locked-in" the scheduling is. You have the options to set priority of sensors by "night, morning, mid-day, and evening". The time periods are all locked and not adjustable. You also can not set priority by the day of the week, it's just one generic priority schedule for every day of the week with locked time periods. Seems like it wouldn't be too difficult to allow this functionality (And for that matter custom label names for sensor/camera/thermostat locations). Final thing to note is the sensor is a lot smaller than I was expecting. About the size of a flattened ping-pong ball, and very light. You also have the option of just putting it on a shelf rather than drilling a hole in the wall and mounting it. Should allow you to experiment with locations or change rooms easily if it's not working exactly the way you want it to. Overall, though, great product, does what it should. Took 1 star off because of the lackluster scheduling that could be improved, and because the setup process did not make a basic check to see if the thermostat was still connected to WIFI and let me waste about 30 mins trying to set it up before I found out myself.

      Simple and effective, long awaited feature

      I have a two story home with only a single zone. The AC system does a pretty good job of keeping temperatures consistent through the house, but it does struggle in moderate weather when it's not running often. It's particularly problematic in the bedroom at night. The thermostat downstairs may think it's cooler than it really is upstairs. Even just adjusting the temperature down doesn't quite work - the temperature upstairs may climb 2-3 degrees before Nest decides its time to cool again. I had tried the Ecobee with its remote temperature sensors. This resulted in wonderful comfort in the bedroom, but their product is plagued with so many issues, one of which being that the Ecobee's remote sensors couldn't even work reliably 30 feet away in my home with almost no obstacles. So far the Nest version of the product is working well. It has no motion sensing option but I can't say I miss it since the Ecobee's didn't really work. More importantly, Nest's sensors range seems better, they are working fine to my office upstairs. Setup was quite simple, mostly scanning a QR code. The Nest app walks you through it. I had no issues. I'm giving it 4 stars because while great, I think they should expand on the functionality provided a bit. An option to average the temperature across multiple selected sensors would be a good idea. I think more customization with the scheduling instead of fixed time blocks. Motion sensor integration could still happen through other products ( Nest protect?). What's offered here happens to fit my needs pretty closely though. I'm happy its here, and I'm happy it works.

      Perfect for hot zones and baby's room

      We have been Nest customers for more than 5 years and we hoped that they would add these a while ago. We moved in to a new build home about 2 years ago and found that some rooms of the house are cooler or warmer than others. The builder had the A/C flows leveled, which certainly helped, but we still have a temperature issue in certain rooms. These sensors work well, but they aren't quite what we were hoping. I included a few notes below..... 1- If you purchase the 3 pack, don't pull the tab to activate the battery until after you scan the barcode. I mistakenly pulled all the tabs and then activated them, but I didn't know which tab was for which sensor. The barcode should be on the item like the rest of the Nest products, not on a pull tab. I ended up having to place them in the sun one at a time to identify which one was for what room. 2- These work VERY well for us monitoring the temperature in our baby room. I will note to not place them directly adjacent to the vent flow, but rather as close to where the baby is sleeping as possible. They mount well and it was great to monitor the temperature in their room. 3- I really wish I could set the temperature to be controlled by different sensors in different parts of the day. I work from home and my office gets very hot at the end of the day. I would love to have it sync with that room during the afternoon and the thermostat for the rest of the evening. Likewise, it would be great to tell it to turn on if the temperature at ANY sensor reaches a certain level. This would be particularly useful when we are cooking dinner and I feel like I'm sweating to death in the kitchen. Perhaps the next version will add this useful functionality. 4- I love that it tells you if the room is typically hotter, colder, or about the same as the thermostat. Our thermostat is in a bad place and we frequently wonder why the A/C has or has not turned on. Overall, we would recommend the sensors and it is probably worth it to get the 3 pack. This feature was needed for a while and we are happy Nest finally offered these as an accessory.

      I bought this temperature sensor to help the Nest Learning Thermostat E control the AC temperature. The problem is most thermostats are installed in the hallway and most hallways don't have vents. This means that the temperature in the hallway is almost always going to be warmer than a bedroom, office, etc. The problem that we had was in the bedrooms it would be hot, so I'd set the thermostat to 74 degrees which read its temp from the hallway, so the bedrooms which are smaller and all have AC vents would get freezing cold. THE SOLUTION This Temperature sensor. I bought one an placed it one of the bedrooms. Now the temperature is being read from the bedroom, and to my amazement, the bedrooms read up to 4 degrees cooler. Now when I set the temp it reads from the smaller rooms, now the temperature in all the bedrooms and the office are pleasant. The only rooms that require the temp to be tweaked is our large living room. That's a simple fix though I can lower the temperature using my phone, Amazon echo or my smartwatch when were in the living room. Install could not have been simpler, open the box, take out the sensor, pull the plastic tab that connects the battery, open the nest app it finds the sensor. THAT'S IT. Well worth the money in power savings and comfort.

      Useful for rooms with large temperature difference

      Our master bedroom is unfortunately built over the garage of our house. It’s not a big deal in the winter. However in the summer this causes it to be scorching. We’ve seen it reach 80 degrees before. To get it anywhere near comfortable we’d have to set the a/c to a much lower temperature than the main floor and wait at least an hour to cool down. Life being life however we frequently forgot to do that until we were getting ready to go to sleep. Which caused uncomfortable nights trying to get to sleep. In a last ditch desperate effort we bought the sensor to hopefully take care of that annoying little chore. And we have to say it works amazing. We can choose when the temperature defaults to the sensor and program in what time we want it to cool down through the Nest Thermostat calendar. You can also manually change between the thermostat and sensors as you please. The only real downside to this is you have a time table you have to pick from for the programmable sensor time ex: 7am - 11am. Which compared to the complete control you have with everything else seems like an oversight. All in all I would give it a 9/10 and will probably be purchasing another for our finished basement come winter.

      Excellent Add-On Temperature Sensor for NEST

      I've been a fan of NEST thermostats for many years and recently added the simple NEST Temperature Sensor to my home's HVAC control system. I noticed that the upper floor of my home never seemed to reach the set point temperature of the NEST Thermostat, thus added the temperature sensor to my master bedroom. Wow - so easy and a great add-on. It basically helps me balance out the control temp in the house by averaging the temps it sees at the main thermostat downstairs and the add-on temperature sensor upstairs. My wife is really impressed too. Gives her the comfort knowing that the tstat will keep cooling system going in the summer time a little longer than before, until the set point is reached upstairs as well. This is a no-brainer to add the NEST Temperature Sensor(s) to any home; especially if you have a multi-floor home or areas that are traditionally much cooler or hotter than others. I definitely recommend this little, affordable temperature to any NEST controlled home. Great Product NEST engineers !

      I have (1) thermostat in the center of my house and suffer from varying room temperatures. Our bedroom can go down to 66 degrees at night when our thermostat says 70 degrees. I just recently purchased a Nest 3rd generation thermostat along with (3) Nest temperature sensors. Last night was the first night using it and our bedroom stayed at 70 degrees! You just go into the settings and tap which sensor you want to go off of and the temperature you want it set at! So easy! I would highly recommend these thermostat sensors to anyone who owns the Nest 3rd generation thermostat and suffers from various temperatures in different rooms! I understand that previous generations are not compatible with this...However, I don't think that it's fair to bash the review on these sensors because it's not a surprise that they don't work on previous generations. Nest states that they only work on 3rd generation thermostats. Does it stink? Yes, and I hope they can come out with something in the future for previous generation owners. But, please do not rate this product bad because of this.

      I just found out these were available and had to have one today! I love how small the device is and it's 2 year battery life. We've struggled with winter temps that always makes us too hot or too cold due to the thermostat reading temperatures in our open living room. Very simple setup as well- just unscrew the back plate and take a QR pic or id# to register it. Install the back, then you're good to go. It can be left on a counter or comes with a screw to mount it as desired. I just think there needs to be a software upgrade that would allow a time frame of when to use the remote sensor and main thermostat. We only use it for when we sleep at night for a more accurate reading. I highly recommend this product to anyone with a Nest that has a oddly cold or hot room as this could solve your issue.
